Question

THe area of a rhombus is 25 cm square AND ONE OF ITS DIAGNL IS 4 FIND PERIMETER

Answer 1

Step-by-step explanation:

In a Rhombus, s1=s2=s3=s4=s

area =1/2×d1×d2

25=1/2×4×d2

d2= 12.5

by pythagoras theorem

d2 ²= d1 ²+ side ²

(12.5)²= (4)²+ s²

s²= 140.25

s= 11.8

Perimeter= sum of all sides

= 4s

=4(11.8)

=47.2 cm
